Filter by:Our main objective is to perform an explanatory, first stage proof of concept, randomized controlled trial to determine whether a semi-upright patient position versus a supine position while asleep in the postoperative period helps decrease the worsening of AHI in patients diagnosed with OSA and compare this to usual care (i.e. supine patient positioning while asleep). The investigators will evaluate whether a semi-upright position reduces: worsening of AHI (as measured with a portable PSG) on the second postoperative night (POD2); oxygen desaturation index (using a portable oxygen saturation monitor, oxygen desaturation defined as >4% change below baseline lasting for 10 seconds); REM sleep related change in AHI at baseline and POD2.; major and minor perioperative complications on postoperative day POD1, POD2, at discharge and POD 30.; length of hospital stay and readmission within 30 days; and patient satisfaction score on POD30
The hypothesis of the study is that a bibloc-apnea splint has a comparable efficacy on respiratory measures as a monobloc-apnea splint and that the cost of treatment is the same. The goal is primarily to compare the Apnea-Hypopnea Index (AHI) after 6 weeks of treatment and the cost of treatment during one year. This randomized controlled parallel group multicenter study includes 316 subjects referred for the treatment of moderate to severe Obstructive Sleep Apnea (OSA). The subjects visit the clinic at 5 scheduled occasions.
The increased risk of atherosclerotic morbidity and mortality in patients with obstructive sleep apnea (OSA) has been linked to hypertension, insulin resistance, dyslipidemia, and systemic inflammation. The relationship regarding obstructive sleep apnea (OSA) and lipidemia and systemic inflammation is far from conclusion for obesity as a strong confounding factor.
The goal of this study is to determine if the investigators can use the STOP-BANG score to identify those patients at risk for worsening Obstructive Sleep Apnea (OSA) symptoms in the early postoperative period after major surgery. Hypotheses: 1. - Postoperative sleep apnea parameters will be worse when compared to baseline in patients with higher scores on the STOP-BANG. 2. - A higher STOP-BANG score will be predictive of worsening sleep apnea parameters in patients undergoing Total Knee Arthroscopy (TKA).
Participants will undergo a normal sleep study. They will be randomised to use either a FPH Pilairo Q nasal pillow CPAP mask, or another mask. The sleep technician will record leak and pressure data, and complete questionnaires regarding satisfaction and ease of use at the end of the night. It is hypothesised that the Pilairo Q mask will be superior to other standard masks for CPAP therapy in terms of ease of use, satisfaction and overall titration experience.
The investigators hypothesized that the treatment of obstructive sleep apnea (OSA) with continuous positive airway pressure (CPAP) will positively affect the appearance of the patient. The purpose of this study was to compare effects of one month of treatment of CPAP and placebo on appearance of patient with OSA in a randomized and crossover study. Consecutive sleepy patients with severe OSA were included. The patients underwent three polysomnograms (PSG): first one to confirm OSA and two additional ones using placebo (nasal dilator) and for CPAP titration before starting each treatment period. All patients were randomly included into two treatment groups: 1) placebo use and 2) CPAP use. After one month with the first treatment and 15 days of washout, patients were crossed-over for the second treatment. Photographs from the patients' faces were obtained in the three experimental moments. The photographs were presented in a random order by the Qualtrics Survey Software, and were evaluated online by 704 observers for quantifying healthy appearance (unhealthy to extremely healthy), attractive (unattractive to extremely attractive) and tired (not tired to extremely tired). Apparent age was also rated for each observer. Quantitative evaluations of the skin characteristics of the patients' faces were also carried out at each experimental moment, including the presence of acne, patches, porosity, wrinkles, texture, and skin tone uniformity, through the capture of images by VISIATM System equipment. During treatment period, the 30 patients (age = 46±9 years, 21 men) wearing placebo intervention on 98% of the nights and adherence to CPAP was 94%, with a mean of 6.0 ± 1.7 hours of use per day of treatment. Observational assessment of the photographs showed that patients were evaluated as being younger after using CPAP (P <0.001), but no quantitative changes in face skin characteristics were observed compared to the baseline and after the use of placebo. Sleepy patients with severe OSA had a younger appearance after one month of CPAP treatment.
Sleep apnea is a common disorder that occurs in 3-10 % of the adult population. This disorder disrupts the architecture and quality of sleep. Continuous positive airway pressure (CPAP) therapy is the standard treatment, but in some cases, it can not be used (patient refusal or intolerance). In these cases, treatment with mandibular advancement devices can bring an improvement in symptoms. Therefore, this study aims to compare the effectiveness of titratable versus active mandibular advancement splints in standard care environment. This will be based on the global response, which includes the apnea-hypopnea index and compliance in severe apnea patients who refused or where intolerant to CPAP. Following their severe apnea diagnosis and the assessment on the feasibility of placing a mandibular advancement device, follow-up visits will be scheduled after 3 months of treatment involving clinical monitoring by a physician and a dentist.
Validation of the patient perception questionnaire relating to CPAP use
Oral appliances are an accepted means to treat obstructive sleep apnea. We propose to develop monitoring sensors that could be inserted into commercially available oral appliances in order to monitor effectiveness of the oral appliances in treating sleep apnea.
The purpose of this study is to determine whether Continuous Positive Airways Pressure (CPAP) improves quality of life, cardiovascular (blood pressure) and metabolic profile (glucose and lipid metabolism) in females with moderate-to-severe Obstructive Sleep Apnea (OSA).
